### Formulas used for Amps to kVA Conversion

### Explanation of the Formulas

**Single Phase AC Circuit**:- In a single-phase circuit, the power (in kVA) is simply the product of the voltage and current, divided by 1000 to convert from VA to kVA.

**Three-Phase AC Circuit (Line to Line Voltage)**:- In a three-phase system with line-to-line voltage, the power is calculated by multiplying the voltage and current, and then multiplying by the square root of √3 (approx 1.7323≈1.732). This accounts for the phase difference in a three-phase system. The result is then divided by 1000 to convert from VA to kVA.

**Three-Phase AC Circuit (Line to Neutral Voltage)**:- In a three-phase system with line-to-neutral voltage, the power is calculated by multiplying the voltage and current, and then multiplying by 3. This is because each phase carries part of the total power. The result is then divided by 1000 to convert from VA to kVA.
